Description

TECHNICAL FIELD

[0001] The utility model belongs to sewage treatment equipment technical field, specifically, relate to water treatment device. BACKGROUND

[0002] In water environment protection, water treatment device plays a vital role, they handle water through physics, chemistry or biology, remove or reduce harmful substances in water, thereby protecting water environment. Coagulation sedimentation tank is one of the commonly used water treatment devices, mainly used for the pretreatment stage of urban sewage and industrial wastewater. The working principle of coagulation sedimentation tank mainly includes coagulation, flocculation, sedimentation and clarification process. First, in the coagulation process, by adding coagulant and stirring, the suspended solids and pollutants in water are coagulated to form larger particles. Subsequently, in the sedimentation process, because the density of the particles is greater than that of water, they will gradually sink to the bottom of the coagulation sedimentation tank. Finally, in the clarification process, the upper water body becomes clearer. Although coagulation sedimentation tank can effectively remove suspended solids and colloidal substances in water, form larger flocs and precipitate to the bottom of the tank, part of the impurities that do not precipitate to the bottom of the tank may float on the water surface. These impurities floating on the water surface may mix in the water, reducing the effect of water treatment. Since coagulation sedimentation tank generally does not have a design to treat impurities floating on the water surface, it cannot clean the impurities on the water surface.

[0003] Chinese utility model patent authorized publication number CN213433158U, application date is August 21, 2020, name is: a water purification treatment device for reducing solid suspended matter; the disclosed device includes a water purification tank, the water purification tank is provided with a water inlet and a water outlet, a coarse grid and a fine grid are sequentially arranged in the water purification tank near the water inlet, the coarse grid and the fine grid are respectively connected with a turnover device for driving them to rotate to the horizontal, the top of the water purification tank is also provided with a scraper, the bottom of the scraper abuts against the rotated coarse grid and fine grid, and the scraper is connected with a driving device for driving it to move horizontally on the water purification tank. The horizontal turnover design of the grid may face the risk of damage in long-term operation. Since the turnover action involves mechanical movement, frequent turnover may cause wear or breakage of the connecting parts.

[0004] For example, the Chinese utility model patent authorization announcement No. CN220047173U, application date is May 24, 2023, and the name is: sewage treatment sedimentation tank; The disclosed structure includes a treatment tank provided with a water inlet groove at one end and a water outlet groove at the opposite end, and a filter device is connected across the treatment tank. The two ends of the filter device are respectively installed in the slide rails provided on the two side walls of the treatment tank. The filter screen of the filter device extends into the treatment tank. The scheme has a filter device across the treatment tank. The filter device drives the filter screen to slide in the treatment tank, which can salvage and treat the lighter floating pollutants in the sewage. The two ends of the filter device are installed in the slide rails on the two side walls of the treatment tank, which can slide in the treatment tank. However, it does not mention whether the filter device has a lifting function. In some cases, the filter screen may need to be adjusted in height according to the amount or size of suspended solids in the sewage to more effectively capture pollutants. If the filter device cannot be lifted, it may limit its ability to adapt to different conditions. In addition, the brush cleaning scheme of the scheme has the problem of incomplete cleaning. SUMMARY

[0005] 1. Problem to be solved

[0006] In view of the technical problems that the filter plate in the existing sewage sedimentation tank cannot be adjusted in height according to the position of suspended solids in the sewage, and the filter plate is not clean, the present application provides a water treatment device.

[0007] 2. Technical scheme

[0008] To solve the above problems, the technical scheme provided by the present application is:

[0009] The water treatment device comprises

[0010] The treatment tank comprises a water treatment coagulation sedimentation tank body, a stand column installed at the corner of the water treatment coagulation sedimentation tank body, a motor adjusting mechanism connected at the top end of the stand column, and a bottom beam connected with the motor adjusting mechanism at the end.

[0011] The lifting assembly comprises a stable frame symmetrically installed on both sides of the bottom beam, a lifting electric push rod installed in the stable frame, a top plate connected with the bottom end of the lifting electric push rod, an outer filter plate perpendicular to the bottom surface of the top plate, and an inner filter plate penetrating the outer filter plate.

[0012] The scraping assembly comprises a connecting frame installed on both sides of the bottom beam, and a scraping plate connected with the bottom end of the connecting frame.

[0013] Further, the outer filter plate and the inner filter plate are each provided with a filter screen, the surface of the outer filter plate and the surface of the filter screen are flush, the motor adjusting mechanism comprises a cross arm a, a lead screw b mounted inside the cross arm a, a drive motor mounted at one end of the cross arm a and driving the lead screw b to rotate, and a sliding block c mounted outside the lead screw b, and the end of the bottom beam is connected with the corresponding sliding block c.

[0015] Further, the connecting frame comprises a top horizontal plate, an upper inclined rod and a fixed rod connected with the scraping plate at the bottom end, and the top end of the connecting frame forms a triangular shape.

[0016] The triangular structure has high stability due to its geometric characteristics, and such a design makes the connecting frame more stable when bearing various forces during the operation of the scraping plate. The triangular connecting frame design enhances the mechanical strength of the entire scraping assembly, enabling it to withstand greater working pressure and impact forces during the scraping process. The stable connecting frame reduces the swinging or vibration of the scraping plate during use, improving the safety of operation. The design of the connecting frame can adapt to different working conditions and conditions, and can maintain good working performance on both horizontal and inclined surfaces.

[0017] Further, the scraping plate comprises a three-dimensional isosceles trapezoidal plate and a long strip block connected with the connecting frame, and the opposite waist surfaces of the isosceles trapezoidal plate are curved, and one side surface of the isosceles trapezoidal plate is attached to the surface of the outer filter plate.

[0018] The design of the isosceles trapezoidal plate makes the scraping plate more closely attached to the surface of the outer filter plate, effectively improving the scraping efficiency and ensuring the removal of floating objects on the water surface. The three-dimensional structure and curved waist surface design of the isosceles trapezoidal plate enhance the mechanical strength of the scraping plate, making it less likely to deform or damage under greater working pressure.

The design of the scraping plate can adapt to outer filter plates of different shapes and sizes, increasing the adaptability and flexibility of the equipment.

[0019] Further, a leakage groove is formed in the waist surface of the isosceles trapezoidal plate of the scraping plate.

[0020] The design of the leakage groove helps to reduce the possibility of blockage during the scraping process, maintaining the continuous working capacity of the scraping plate and avoiding equipment failure due to the accumulation of impurities. The presence of the leakage groove enables the scraping plate to more thoroughly remove impurities from the surface of the outer filter plate during the scraping process, improving the cleaning effect.

The rotation mechanism of the blocking plate can reduce the risk of damage to the filter plate when taking out the inner filter plate, protecting the integrity of the filter plate. The design of the blocking plate enables the device to adapt to different filtering needs, especially in applications that require frequent replacement or cleaning of the filter plate.

[0023] Further, the water treatment coagulation and sedimentation tank body is provided with an impurity receiving assembly at the side position, the impurity receiving assembly comprises a receiving box, an extension pipeline in communication with the inside of the receiving box, and a blocking plate connected to the extension pipeline.

[0024] The right-angled trapezoidal shape of the receiving box and the recessed receiving groove on the top help to concentrate the collected impurities, improving the collection efficiency. The impurities can directly fall into the receiving box through the leakage groove, simplifying the cleaning process and reducing the need for frequent cleaning.

[0025] Further, the receiving box is a three-dimensional right-angled trapezoidal shape, and a recessed receiving groove is formed on the right-angled surface of the top of the receiving box, the extension pipeline has a "U" shaped structure, and the blocking plate has a vertical folded edge on the top.

[0026] The "U" shaped cross-sectional structure of the extension pipeline 52 provides additional space for guiding and collecting impurities, while reducing the risk of pipeline blockage.
